A picture of an alleged iPhone 5 digitizer appeared on a Chinese website dealing with Apple components and, if even close to being real, could give us some indications on what really Apple is preparing for this summer.

While this is yet to be filed under capital “R” category, the purported digitizer shows a larger, probably 4-inch display, which fits pretty good with recent rumors floating around. We even talked about this in our latest episode of the Pocketnow PocketCast (that is Episode 4, at 22:00). One other thing to notice is that probably, again, if the picture is to be believed, the iPhone 5 will feature an edge-to-edge display.

This would not only look great but it could serve as a means to obtain a larger screen while not affecting (or minimizing the changes to) the outer dimensions of the phone. Last but not least, on the same note, the component pictured seems to have a whole at the bottom, which could indicate that the next iPhone will still have its Home Button, contrary to previous reports on iOS 4.3 killing it.
